Offensive Patent Portfolio Races

Abstract: In a patent portfolio race, firms attempt to assemble a large collection of patents. Traditional explanations for patent portfolio races rest on an assumption of fragmented patent ownership where multiple unknown firms employ defensive strategies to forestall holdup. However, patent portfolio races can be observed when patent ownership is concentrated to the hands of a few firms. To explore patent portfolio races under conditions of concentrated ownership we turn to the newspaper printing machine industry, an … Show more

“…Successful patent applications are a well‐established invention indicator, but they mainly summarize the number of technological inventions. They may suffer from strategic motives such as protective patenting, which inflates the number of patents and lowers the validity of patent counts (Artz et al, 2010; Blind, Cremers, and Mueller, 2009; Jell, Henkel, and Wallin, 2017). To ensure that our patent‐based analysis captures the relevance of firms’ inventions, we reestimated our models using patent citations as a dependent variable.…”

“…With regards to open innovation, a number of areas have been studied, such as motivations (Appleyard & Chesbrough, 2017) and trade-offs between openness and protection (Raasch et al, 2009;Knudsen & Mortensen, 2011). In the area of IP protection, several papers have dealt with how organizations make protection decisions (Gallié & Legros, 2012), the use of licensing (Gallié & Legros, 2012;Großmann et al, 2016), standard catch-up collection and use of patents (Schmidt, 2013;Jell et al, 2017).…”

“…Defensive strategies seek to provide a firm the freedom to operate and commercialize its invention without hindrance from patents that belong to others (Rudy, & Black, 2018;Somaya, 2012). They are helpful when there is high fragmentation in the market for patentees, and firms are unable to arrange licensing due to transaction costs (Jell et al, 2017). Defensive strategies are thought to be reactionary, focused on protecting the current value of IP (Somaya, 2003;Rudy & Black, 2018 (Rudy & Black, 2018).…”
